Adjustable steering apparatus

Abstract

An adjustable steering apparatus includes: a movable bracket to which a steering jacket including a steering wheel is fixed and to which a movable telescopic member having a tooth portion is fixedly mounted; a stationary bracket which is disposed externally of the movable bracket and fixed to a vehicle body, and to which a stationary tilt member having a tooth portion is fixedly mounted; a movable tilt member having a tooth portion meshingly engageable with the tooth portion of the stationary tilt member; and a stationary telescopic member having a tooth portion meshingly engageable with the tooth portion of the movable telescopic member. An elastic body for release from meshing engagement is disposed on an outer side of the stationary bracket, the elastic body being capable of urging the movable tilt member away from the stationary tilt member. The movable tilt member is engageable with the stationary telescopic member in order that the movable tilt member being disengaged from the stationary tilt member can bring the stationary telescopic member out of engagement with the movable telescopic member.

1. An adjustable steering apparatus permitting tilting and telescopic motions of a steering wheel, comprising:
 a movable bracket to which a steering jacket including the steering wheel is fixed and to which a movable telescopic member having a tooth portion is fixedly mounted; 
 a stationary bracket which is disposed externally of the movable bracket and fixed to a vehicle body, and to which a stationary tilt member having a tooth portion is fixedly mounted; 
 a movable tilt member having a tooth portion meshingly engageable with the tooth portion of the stationary tilt member; and 
 a stationary telescopic member having a tooth portion meshingly engageable with the tooth portion of the movable telescopic member, 
 wherein an elastic body for release from meshing engagement is disposed on an outer side of the stationary bracket, the elastic body capable of urging the movable tilt member away from the stationary tilt member, 
 wherein the elastic body for release from meshing engagement includes a pair of tongues raised in a direction to be spaced away from the outer side surface of the stationary bracket, 
 wherein a release plate is disposed between the movable tilt member and the stationary tilt member, the release plate being capable of being pressed against the movable tilt member and of pressing the tongues toward the outer side surface of the stationary bracket, and 
 wherein the movable tilt member is engageable with the stationary telescopic member in order that the movable tilt member being disengaged from the stationary tilt member can bring the stationary telescopic member out of engagement with the movable telescopic member. 
 
   
   
     2. The adjustable steering apparatus according to  claim 1 , wherein the movable tilt member is formed with a flange which engages with an engaging portion formed on the stationary telescopic member when the movable tilt member is axially moved toward the outer side.
